Complete support for fast8: - amend shadow size and mapping in runtime - remove fast16 mode and -dfsan-fast-16-labels flag - remove legacy mode and make fast8 mode the default - remove dfsan-fast-8-labels flag - remove functions in dfsan interface only applicable to legacy - remove legacy-related instrumentation code and tests - update documentation.
